The smallest pump out there that works?

[sulp]

I was wondering what you guys recommend for the smallest pump out there right now that does a half decent job. I haven't really had the need for one in about a year so I am sure there are some newer smaller ones out there that I am not aware of.

I want something really small to fit behind my aquascaping to keep water flowing through the back of the tank.

Also, What is a good pump to replace the stock pump in the nano with? I'm hearing different opinions. Maybe I'll use the stock pump to circulate the back of the tank if I can't find anything smaller.

I have a JBJ 12g nano.

Thanks!
